My favorite Git Setting

For Ubuntu

function git_branch {
    ref=$(git symbolic-ref HEAD 2> /dev/null) || return;
    echo "("${ref#refs/heads/}") ";
}

function git_since_last_commit {
    now=`date +%s`;
    last_commit=$(git log --pretty=format:%at -1 2> /dev/null) || return;
    seconds_since_last_commit=$((now-last_commit));
    minutes_since_last_commit=$((seconds_since_last_commit/60));
    hours_since_last_commit=$((minutes_since_last_commit/60));
    minutes_since_last_commit=$((minutes_since_last_commit%60));
    
    echo "${hours_since_last_commit}h${minutes_since_last_commit}m ";
}
